bitfirst(binary)
Returns the number of the most significant bit with value 1 in a binary field.
The parameter can be a Binary or an Integer; in the case of Binary, you need to provide a variable, and not the result of a calculation.
The following example sets lNumber to the bit number of the first bit set to 1. If all bits are zero, bitfirst() returns -1.
Calculate lNumber as bitfirst(lBinary)
